Say (Prophet Muhammad): 'O people, I have been sent to warn you plainly. 49 So those who believed and did good deeds, for them are forgiveness, and an excellent sustenance. 50 whereas those who strive against Our messages, seeking to defeat their purpose - they are destined for the blazing fire. 51 And all the Noble Messengers or Prophets whom We sent before you – it occurred with all of them – that whenever they recited (the message) Satan included a bit (from his own speech) in their recitation to the people; so Allah obliterates what Satan includes and then Allah fortifies His verses; and Allah is All Knowing, Wise. 52 This is in order to make the interpolations of Satan a test for those whose hearts are diseased and hardened: Surely the sinners have gone far in dissent. 53 so that those who have received knowledge would know and believe that whatever happens with the Prophets and Messengers is the Truth from their Lord and will believe it. This will cause their hearts to become filled with awe. God guides the believers to the right path. 54 Those who reject Faith will not cease to be in doubt concerning (Revelation) until the Hour (of Judgment) comes suddenly upon them, or there comes to them the Penalty of a Day of Disaster. 55 On that Day all sovereignty shall be Allah's and He will judge among them. Then those who believed and acted righteously shall be in Gardens of Bliss. 56 whereas for those who were bent on denying the truth and gave the lie to Our messages, there shall be shameful suffering in store. 57
